f Figure 10. Figure 12 on the indicated line In the construction of the improvement as shown, a suitable stand support for steam boardis illustrated as comprising a base plate 15 adapted to rest face and a pedestal O l6 fixed to and rising from floor or similar sursaid plate 15, said pedestal preferably being substantially perpen dicular to the plane of the indicated line;

said plate and, for convenience, being curved approximately as shown in Figure l. The plate and pedestal illustrated and described may well be formed as an integral casting or molding, but may obviously be constructed in any manner and form suitable to their function. The upper end of the pedestal 16 is shaped to conform to and fit snugly within a side-opening recess 17 formed in the lower portion of an integral operating head 18, whereby said head 18 may be mounted on and supported above said pedestal, a web of said head 18 extending across one side of the upper end of said pedestal and being formed with a hole 19 in registering relation with a similar hole in and through said upper end of the pedestal to receive a bolt 20 extending through said web and the upper end of said pedestal to firmly clamp and hold said head 18 to and on said pedestal. To prevent relative rotation between the head 18 and pedestal 16 about the bolt 20 as a pivot, a second hole 21 is formed in the lower portion of said head perpendicular to the hole 19 to receive a bolt or screw 22 engaging in or hearing against the rear face of said pedestal. A relatively long hollow casing or shell 23, perforated on its upper surface and preferably tapered to a reduced end portion in elevation and plan, is provided with a closed outer end and is rigidly secured at its open inner end, preferably by welding or brazing, to one face of the head 18, so that said shell 23 extends in substantially a horizontal plane laterally from said head in parallel relation with and above the longer axis of the base plate 15. The shell 23 is preferably substantially oval in section and for practical purposes is preferably covered with a. porous pad 24 and a fabric cover 25,.sa-id pad and cover being formed of material through which steam may readily pass. An imperforate tube 26, having a closed outer end,-is mounted longitudinally within and in spaced relation with the inner walls of the shell 23, the open inner end of said tube 26 being received in threaded or other suitable sealed engagement in a bore formed in the head 18 and opening into the interior of the shell 23, the closed end of the tube 26 extending adjacent the closed end of the shell 23, thus forming non-communicating compartments within said tube and said shell. A bore 27 is formed in and through the head 18 in axial alinement and concentric with the tube 26, the inner end of said bore serving as a seat for a tube 28, open at both ends and longitudinally disposed within the tube 26, spaced from the inner walls of said latter tube and extending adjacent the closed end of said tube 26, a pressure pipe 29, leading from any suitable source of steam (not shown) being seated in and communicating with the outer end of the bore 27, so that steam passing through the pressure pipe 29 is discharged through the bore 27 and tube 28 into the interior of the tional area of the imperforate tube 26 adjacent its outermost end, filling the space between the tubes 26 and 28 and heating these elements of the device. In order to provide for continuous circulation of steam in and through the tubes 26 and 28, a return steam line 30 is mounted at one end in the head 18 spaced from and below the pressure pipe 29 and connects said head with the return port of the source of steam, a passage 31 formed in the head 18 providing con'nnunication between said return pipe and the space between the tubes 26 and 28, so that steam discharged from the tube 28 adjacent the outer end of the tube 26 moves rearwardly toward the head 18 through the space between said tubes and is returned to the source of steam through the passage 31 and return pipe 30, the cross secpassage 31 being less than that of the tube 28 to insure that the space between the tubes 26 and 28 is at all times filled with steam under a degree of pressure. Valves may be installed in either or both of the pipes 29 and 30 to control the passage of steam therethrough, but when the device is arranged for practical use it is intended that said pipes 29 and 30 shall be free and unobstructed and that steam shall circulate freely and continuously through said pipes, the passage 31 and the tubes 26 and 28, to the end of heating the recited elements and consequently heating the shell 23 and head 18 as well. The elements of the device above described constitute the heating unit and the shell 23 forms the steaming buck on which the fabric or garment to be steamed is supported. A vertical, downwardly-opening bore 32 is formed in the head 18 at one side of and spaced from the bore 27 and communicates with said latter bore through a steam passage formed in the head 18. The upper, inner end of the bore 32 is provided with a downwardly-extending annular rib 34 through which a steam passage 35 extends upwardly and forwardly of the head '18 to connect the bore 32 with the space between the shell 23 and tube 26, thus providing means whereby steam may pass from the bore 27 through the passage 33, upper end of the bore 32 and passage 35 to the interior of the shell 23. Since continuous flow of steam into the shell 23 is unnecessary and would result in excessivewaste of steam, valve means are provided to normally interrupt said flow, said valve means comprising a valve stem 36 positioned axially of the bore 32, slidingly mounted in and through a packing gland 37 closing the lower end of said bore and projecting below said gland to terminate in a clevis 38 adjustably threaded on the lower end of the stem. The upper end of the stem 36 is formed as a head 39 on which is removably and replaceably mounted a valve disc 40 substantially filling the bore 32 and formed with an annular recess in its upper face wherein is Y 401011 its upper headed end and the upper space between vseated a disc of yielding material 41 in opposition to and adapted to seat againstand form a seal with the annular rib 34 when the valve vassernb ly is pressed upwardly against said rib, as shownin the drawings. It is obvious that withthe valve assembly inthe position shownno steam can pass through the passage -33iand into-thepassage35. and leakageof steam .from the bore 32 is prevented by the i e hereinafter more spec fically described, as

will also hethe pedalmeans operable to open the valve assembly. In like manner, a vertical,downwardly-opening bore 42 is formed in .the head 18 parallel, with and spaced on the opposite sideof the bore 27 from the bore 32 and communicates with said bore 27 through asteam passage 43 formed in said head. lihe inner end of the bore 42 is provided with an annular rib 44 identical with therib 34 of the bore 32 against which is normally seated the sealing disc 41 of a valve assembly identical with that above described for the bore 82-, said valve assemblyin the bore 42 comprising a stem 36',havi ng a head39', slidingly mounted through a packing gland 37 in the lower end of said bore 42'and carrying the valve disc an adjustable clevisv38 on its lower end. A steam passage extends frointhe inner end of the bore 42 upwardly throu, "l 1 the rib 44 and within the head 18wheresaid passage is curved forwardly and then downwardly to communicate with end of a relatively large, clownwardly opening bore 46 spaced from and parallel. with the bore 42, an exhaust pipe 47 being seated in the lower end of the bore 46 and leading to any suitable point of discharge, such as adrain or receptacle. Adjacent and forwardly of the bore 46, a bore 48 is provided in the head 18 and aesteam passage 49 connectsj theinner end of the bore 48 with the the shell 23 and tube 26, communication v between the inner ends of the bores 46 and 48 being had through a passage 50 therebetween. The innerend of the bore 48 is formed as a seat for a plain valve 51 carried by asstem52 mounted for vertical reciprocation through a packing gland 58 closing the lower end of said bore, the lower end of said ste1n52 extending below the gland 53 and beingprovided with anadjustable clevis 54 similar to the clevises 38 and 88. With the construction above described,it is obvious thatjwhen; the valvesin the bores 42 and 48 are closed against their respective seats, no steam may pass from the bore 27 to-the bore 46, nor may'steain or air pass fromwithin the Sh l 2 t that-0. 4 howev r,- n the action produces a .rise from the rearward an opening formed .bers59 and 60, respectively,

,Of' the base plate.

passage 43 into the bore 42 and thence through the passage 45 from whence it is discharged as a et into the bore 46, which jet lowered pressure in the upperend of the bore 46 andetiects a suction actionthrough the passage 50, bore 48 and passage 49 to withdraw steam from the 1nterior of the shell 23 for dischargethrough the exhaust pipe 47 together with the steam from the jet. The suction action'above de scribed causes fair to be drawn through the material being treated on the buck and into the interior of the shell 23, thuscompletely removing any steam from said material and thoroughly dryingandcooling the same.

From the foregoing description; it is ob .vious that the valve .5 1; should beclosed when the valve assemblyinthe bore-.32 is opened .forthesteaming operation, thus preventing waste of steam through the exhaust pipe47, and that said valve 51 should operate simultaneously with the valve assembly in the bore 42 for the desired suction effect. Any suitable arrangement may ,beprovided for the selectivecontrol of the valves employed in ithedevice, a preferred and most convenient form of pedal.control leaving the hands of the operator terial being treated, being illustrated and hereinafter described. *Spaced supports 55 end of the base plate 15 on opposite sides of the longitudinal nedian line thereof and support a pivot pin 56, in horizontal position transversely of and above; said base plate, Levers 57, 58 are pivotally secured at one end each to the pin 56 and extend in parallel, adjacent relation longitudinally of the base plate 15 and through pedestal 16, to support adjacent pedal memon their free forward tends above said base plate. The

lever 57 is preferably longer than the lever 58 and inclined throughout the major portion ,of-its length below the position of the lever .58, both of said leversbeing curved upwardly adjacent. their free ends .topermit-the pedals 59 and 60 to normally lie in a common plane and in substantial 'alinement longitudinally The base plate 15 is also preferably slotted beneath the lever 57 to give added range of movement to said lever and a stop 61 is formed on said base plate beneath thepedal GO toengage said pedal when the same isdepressed and arrest its downward 3 movement to prevent its contacting with and operating the lever; 57. The clevi'ses 38 and 54 are connected for simultaneousoperation by a yoke62, the mid-portion of said yoke being pivotally connected with the lever 58 by means of'a pull rod 63, so that, when the pedal 60 is depressed, a pull is exerted on the e e 2 hr ugh the rod. 3 wh h. serves t free for manipulation of the main the lower end of the simultaneously unseat and open the valves in the bores 42 and 48. In llke manner, the

' clevis 38 is pivotally connected with the lever 57 by means of a pull rod 64, so that, when the pedal 59 is depressed, a pull is exerted on the y'alve stem 36 through the rod 64,

which serves to unseat and open the vah'e in the bore 32. A stud extends rearwardly from the pedestal 16 on the longitudinal line of the base plate 15 and above the levers '57 and 58, said stud terminating in an apertured end between the pull rods 63 and 64 and serving as a guide for the tree lower end of a. pin 66 vertically supported between said rods 63 and 64 by and pivotall depending from a yoke 67 carried in and bridging between registering apertures in said rods, said pin 66 forming the slidable core for an expansible coil spring 68 confined between the enlarged upper end of said pin and the rearward end of the stud 65. From the construction shown and described, it is apparent that the expansive force of the spring 68 is exerted against the yoke 67 in an upward direction to normally lift the rods 63 and 64 and hold the valves in the bores 32, 42 and 48 in closed position, at the same time lifting the levers 57 and 58 to bring the pedals 59 and 60 into operative posit-ion, depression of either pedal operating its respective pull rod and "alve or valves against the pressure of the spring 68 without disturbing the other pedal or its connections. Since no good pur pose is served by opening the valve in the bore when the valves in the bores 42 and 48 are open, and vice versa, it follows that the pedals 59 and 60 need never be operated siniultaneously, hence the operator can con trol the apparatus with but one foot and by simply shifting from one pedal to the other, a distance of but a few inches.

In the modification shown in Figures 10 and 11, the operating head, pedestal and control system is essentially the same as above set forth, the only difference being in the construction and arrangement of the elements comprising the steaming buck and heating chamber. In the figures last above noted, the the tube 26 is replaced by a tubular extension 26 formed integrally with the head 18 into which the bore 27 opens directly and the tube.

28 is replaced by a tube 28 communicating directly with the return pipe 30 through the passage 31, saidtube 28 being open at both ends as was the tube 28 and the extension 26 being closed at its outer end and imperfora-te, so that steam from the bore 27 is carried to the outer end of the extension 26 and thence returned through the tube 28 and returned through the pipe 30, thus reversing the circulation ofsteam within the heating chamber as formerly described. The extension 26 is stepped down below the top of the head 18 and a thin metal plate 23, perforated as Was the shell 23, is substituted for said shell and spaced above the extension 26, said plate being curved to contact with said extension and be marginally sealed thereto, the passages 35 and 49 obviously opening into the space between the plate 23 and extension 26.

Any suitable table or'other'means for supporting the overhang of material being treated may be employed with the machine, a convenient and preferred form bein illustrated as comprising a troughed ta le 69, having upwardly diverging side portions, said table being positioned beneath the steaming buck and supported at one end by suitable clamping means 70 fixed to said table and engaging an eye 71 carried by the pedestal 16, the outer end of the table being provided with suitable legs 72 engaging the floor or other surface supporting the steam board.

In the practical operation of the improved steam board, steam under pressure is circulated continuously within and through the heating chamber formed by the tubes 26 and 28 or the elements 26' and 28, the steam in each case entering theheating chamber at one end and escaping therefrom at the other end, so that an even temperature is at all times maintained in the heating chamber and steaming buck, said temperature being high enough to prevent condensation of any steam and insure against wetting of the material to be treated. The material to be treated having been placed over the steaming buck, the pedal 59 is depressed to open the valve in the bore 32 thereby admitting steam from the pressure line into the shell 23, from whence it escapes, the valve 51 being closed, through the perforations in said shell to produce the desired effect on said material. The steaming operae tion is continued as long as may be desired,

then the valve in the bore 32 is permitted to close and the pedal 60 depressed to open the valves in the bores 42 and 48, producing the jet effect in the bore 46 resulting in a suction eitect through the shell 23 which operates to withdraw steam from said shell and to draw air through the material being treated, into said shell, thereby thoroughly removing the steam trapped in said material and drying and cooling the said material, during all of which operations the heating chamber continues to function.

Since many changes and modifications of the form and construction of the elements comprising the improvement may be had withoutdeparting from the spirit of the invention, I wish to be understood as being limited solely by the scope of the appended claims rather than by the illustrative showing and foregoing description.
